Rick Prime

Masochist. He is the Rick Sanchez who invented interdimensional travel first and offered it to other Ricks, abandoning his own family because he viewed emotional attachments as a weakness. When the protagonist (Rick C-137) rejected his portal technology offer, Rick Prime dropped a b..0-mb through a portal that k**led C-137's wife, Diane, and young daughter, Beth. Unlike other variants who eventually sought family or comfort, Rick Prime completely rejected familial love and even created the Omega Device to erase every version of Diane across the entire multiverse. Rick C-137 tracks him down and brvtally b*34t_s him to d**th in Season 7, though the victory leaves C-137 emotionally unfulfilled and still grieving. (please don't mind the voice)
